FOUNDATION FOR CARD-CLOTHING.

Specification of Letters Patent.

Application filed April 13, 1915. Serial No. 21,171.

T 0 all whom it may concern:

Be it known that I, HERBERT Minster, aciti-zen of the United States, residing at orcester, in the county State f Massachusetts, has invented certain new and useful Improvements in Foundations for Card-Clothing, of which the following is a specification.

In the customary use of card clothing as heretofore manufactured, a prevailing source of annoyance, trouble and expense has always existed by reason of the stretching, to a greater or less degree, of the foundation in which the card-teeth are supported; and this stretch, though but slight at any one portion of the card-clothing, frequently amounts to quite a serious defect, as the strips of card-clothing, after they are spirally wound tightly upon the cylinders, workers or rolls (the usual. method of applying clothing in carding machines) and put. to use, will by such stretching of their back ing, become loose and tend to crawl toward the rearmost end of the strip orcoiL'bulging or increasmg to an appreciable degree the of the roll, 01' cylinder, thereby rendering the cooperating faces of the lickers-in, workers, dolfers and main carding cylinders inaccurate, irregular and variable in action and wear; and soon destroying the uniformity of the cardingfaces so that the mechanism is incapable of doing perfect carding work; furthermore requiringtoo frequent .regrinding and areclothing of the cylinders and carding rolls, and other repairs. Especially is thisstretching of the foundation a source of loss and expense if any extremedampness or water comes in contact from the discharge of automatic sprinklers, or other wet-downs, as may sometimes occur.

The object of my present invention is to noted deficiencies or oband to provide a card-clothing that willnot stretch andbecome loose after it is arranged upon the carding machine; also to provide a practicable ,and efiicient nonstretchable foundation for supporting the card-teeth While affording the requisite firmness of set in the backing. and suitable yieldovercome the above jections,

further object is to provide a cardclot-hing having a water-repellent, oil proof,

of Worcester and with the card-clothing, ash

non-stretchable flexible foundation of the character and material specified, as an improved article of manufacture. v

hese objects I attain by the means and construction illustrated and fully described, the particular subject matter claimed being hereinafter definitely specified.

In the drawings, 7 longitudinal section of card-clothing emodying my invention; one end of the piece shown dissected to more clearly reveal the structure. Fig. 2 represents a plan or face view of the same. Fig. 3 is a modified sec tion view showing the card-clothing as made with a comparatively thin foundation or body adapted for slender teeth. Fig. 4 is a fragmentary section view illustrating the described structure, the parts being drawn to a somewhat enlarged scale.

invention consists in a card-clothin forth, resulting in a non-stretching, Water proof and oil-proof backing of a firm and Referring to the drawings, the letter A indicates the card-strip, foundation or bodv.-

which, as shown, includes the solid backing portion 3 and united facing portion 4. The backing 3 is, in accordance with my invention, composed of strong close meshed woven fabric, preferably cotton duck 2, having the surfaces thereof coated, and the meshes of the fabric impregnated and filled with the oil-proof, water as balata, or balata gum compound.

As many plies or layers of said treated or balata-filled woven duck 2 the required thickness of backing 3 in any instance, are superimposed one upon another, for combining together with the balata compound, '5, and the whole compressed and conso ated into a compact integral body of uniform density. 1

Upon one side of this backing 3, and firmly cemented thereto at the meeting surface line 6, I arrange the facing portion 4 which is repellent substance known- Patented Feb. a, rare.

as will give strong of fibrous material, preferably wool felt or woven woolen cloth fabric, which may if desired, be formed in one or more plies united to give the desired amount of thickness as in any particular instance desired.

In some instances a ply or plies of comparatively fine-meshed canvas or the like 2*, treated with the balata material, may be securely cemented between the felt facing portl on 4 and backing 3; an instance of such method is illustrated in Figs. 1 and 2. The

-fine meshed canvas may be omitted when so preferred. y

The Wire card-teeth C are set, in usual manner, through the solidly compressed impregnated ,woven duck backing 3, and project up through the'fibrous felt or woolfabric facing 4 which latter afiords'a cushion or .degree of elastic action'to the teeth.

The thickness of, the backing 3 may. be

. made more or less, to meet the requirements for the various different grades of card- 4 may complete foundation A. A heavier backing I 3 makes a stiffer card and supports or holds the teeth C more firmly than does the lighter backing; while a heavier or thicker facing f1 makes a more yieldable cushioning support for the teeth than does a thinner facing.

It will be understood that I do not claim broadly the idea of making up card clothing foundation ofdifi'er'ent layers, or the idea of a soft fibrous facing element in a card clothing, irrespective of the specific construction specified and hereinafter de-.

fined.

What I claim and desire to secure by Letters Patent,isp j 1. The within described card-clothing, in

which the tooth-holding foundation consists of strong close-woven cotton duck with its meshes filled, solidified and united with a comparatively hard slightly flexible balata substance integrated therewith, a ply of comparatively fine textile fabric adhesively attached to the face thereof, and wireteeth inserted therethrough, the whole forming a substantially non-stretchable, Water-repellent, oil-proof card-clothing structure, as set forth.

2. A card-clothing foundation comprising a back portion including a plurality of layers of woven cotton-duck, its mesh impregnated and solidly united with a slightly flexible hard-balata filling, and a face ply of non-impregnated fibrous fabric.
